I haven't worked with parallels so I can't comment either.
I've done VMWare server with various combinations. Linux guest on linux
host seems to be the most bang for the buck. I'd done a W2K and WXP host
and it performed like a dog, granted memory may have been a constraint.
I've also noted that XP guest (with all the fancy UI stuff turned off) is a
pig. CPU used by the VM on the host commonly runs >100% for a 1CPU VM. I
haven't done Windows Server guest, yet.
I don't have a data point for ESX yet but it should be more efficient since
it runs on bare metal, no host OS. We have licenses and will be migrating
current real servers to VMs on ESX for the disaster recovery and load
balancing benefits. Hopefully that will happen some time in October as time
permits. I can probably provide more insight then.
Our hardware is a pair of IBM eServer 326's with Opteron 265's (1.8GHz,
dual core). CPU has not been a problem, although disc I/O gets taxed at
times.
